Figure 1 is a schematic view of the assembly. As shown in FIG. 1, the assembly includes a tablet electronic device 110 and an auxiliary heat dissipating member 120, wherein the tablet electronic device 110 and the auxiliary heat dissipating member 120 are in an unassembled state.

The auxiliary heat dissipation member 120 includes a base 121, a base heat sink 123, and a heat conductive plug 124. A perspective view of the auxiliary heat dissipating member 120 is included in FIG. 1, and FIG. 2 shows a top view of the auxiliary heat dissipating member 120, in order to be able to clearly see the respective components, the top cover of the auxiliary heat dissipating member 120 is removed. The auxiliary heat dissipating member 120 will be described in detail below with reference to FIGS. 1 and 2.

As shown in Figures 1 and 2, in one embodiment, the base 121 is generally flat and rectangular. Body shape. In other embodiments, the pedestal 121 may have other geometric shapes, such as a generally pyramid, a cone, a frustum of a pyramid, and a frustum of a cone. , spherical, hemispherical, spheroidicity or other prisms other than the aforementioned shapes and other polyhedrons. The base 121 can also be industrially designed to promote the aesthetics, ergonomics, functionality, and usability of the device.

Again, in an embodiment, the base 121 can be designed for a particular purpose. For example, the base can be configured to have a shape such that the base can be easily tethered or secured to the dashboard within the vehicle. Of course, in these examples the base 121 may also have a securing member to secure it at the desired location.

In an embodiment, the top of the base 121 is provided with a recess 122 for receiving a portion of the tablet electronic device 110. The recess 122 can be configured to match the shape of the portion of the tablet electronic device 110 to be accommodated to provide a fixation when the tablet electronic device 110 is placed on the base 121.

The susceptor 121 provided by the present invention includes the various features described above.

The susceptor heat sink 123 is disposed in the susceptor 121. In order to prevent dust or collision on the base heat sink 123, the base heat sink 123 may be surrounded by the base 121. In order to improve the heat dissipation effect, the susceptor 121 may expose a part or all of the susceptor heat sink 123. The pedestal heat sink 123 may include one or more of a heat sink, a heat pipe, a fan including a normal fan and a turbo fan.

The first end of the thermal plug 124 is in thermal contact with the pedestal heat sink 123, and the thermal plug The second end of the head 124 extends upward from the bottom of the recess 122 for insertion into the thermal socket 111 (see FIG. 4) of the tablet electronic device 110 when the tablet electronic device 110 is placed on the base 121. During operation of the tablet electronic device 110, heat generating components (such as a processor, a storage device, a graphics card chip, and/or a power source) in the tablet electronic device 110 continuously generate heat, and the susceptor heat sink 123 has a heat dissipation function. Therefore, the first end of the thermal plug 124 is a cold end and the second end is a hot end.

The hot end draws heat from the tablet electronic device 110, causing the temperature of the two ends of the heat-conducting plug 124 to be unbalanced, so that heat is continuously transmitted from the second end of the heat-conductive plug 124 to the first end, so that the flat-panel electronic device 110 and the auxiliary heat-dissipating member can be A heat transfer path is formed between 120. In this way, the heat generated by the tablet electronic device 110 is quickly diffused into the environment, preventing excessive heat accumulated in the tablet electronic device, and avoiding heat accumulation to limit the performance of the tablet electronic device.

It can be understood that since the heat sink 123A is disposed in the susceptor 121, in order to allow heat to be diffused into the environment, the susceptor 121 should be provided with a heat dissipating mechanism. When the susceptor 121 is a sealed structure, the heat dissipation mechanism may be a heat dissipation opening 125, which may be disposed in the vicinity of the heat sink 123A (eg, the side wall of the susceptor 121, the bottom cover, and/or the top cover).

A fan 123B is disposed beside the heat sink 123A and on a side opposite to the heat dissipation opening 125, and an outward flowing airflow can be formed inside the susceptor 121, and the airflow can quickly dissipate heat on the heat sink 123A through the heat dissipation opening 125. In the environment, heat dissipation efficiency is improved, and on the other hand, dust can be prevented from entering the susceptor 121. In one embodiment, the fins 123A are disposed perpendicular to the sidewalls provided with the heat dissipation openings 125 to form the shortest airflow path, thereby improving heat dissipation efficiency.

In an embodiment, the fins 123A are disposed in parallel with the grooves 122. 3 is a schematic illustration of a thermally conductive plug in accordance with one embodiment of the present invention.
